The German Shepherd Dog (GSD) is perhaps best known as the strong, courageous and obedient guide dog for the disabled and service dog of police K-9 and search-and-rescue units, valued for its tenacity, intelligence, loyalty and focus. GSDs are often sought as guard dogs and protectors. However, while they are first and foremost a herding, GSDs can make outstanding, loving family companions. German Shepherds have a rather distinct personality marked by a direct and fearless expression, obvious self-confidence and reluctance to develop indiscriminate friendships. They tend to be indifferent to strangers and can be aloof; however, once they befriend you, their devotion is life-long.
